What is Identity & Access Management (IAM)? Everything you need to know
Organizations today work with countless systems, applications, and data sources. From HR systems to financial software, and from email to cloud platforms. All these tools must be safely and efficiently accessible to employees. But how do you manage that wisely, without endless manual administration? The answer is Identity & Access Management (IAM). In this article, we explain what IAM is, why it is crucial for modern organizations, and how it helps your company work more securely and efficiently.

Organisations today work with countless systems, applications, and data sources. From HR systems to financial software, and from email to cloud platforms. All these tools must be securely and efficiently accessible for employees. But how do you manage that cleverly, without endless manual administration?
The answer is Identity & Access Management (IAM). In this article, we explain what IAM is, why it is crucial for modern organisations, and how it helps your company work safer and more efficiently.
What is IAM?
Identity & Access Management (IAM) is the process by which organisations manage digital identities and determine who gets access to which systems and data.
With IAM, you ensure that:
The right person gets access to the right information,
At the right time,
And under the right conditions.
In short: IAM is about “the right access, for the right person, in the right way.”
Why is IAM important?
Security and compliance
IAM helps prevent data breaches and supports compliance with laws and regulations such as GDPR and ISO 27001. Access to sensitive data can be restricted to only those who truly need it.Efficiency for HR and IT
Without IAM, HR and IT departments spend a lot of time manually creating, modifying, or closing accounts. IAM automates this process, ensuring employees have immediate access to the right systems upon joining, and accounts are automatically removed upon leaving.Better user experience
IAM makes employees' work easier. With Single Sign-On (SSO), they log in once to access all necessary systems. Add Multi-Factor Authentication (MFA) to this, and you combine ease of use with extra security.
How does IAM work in practice?
IAM often consists of a combination of:
Provisioning – automatic assignment and revocation of rights.
Authentication – verifying whether someone really is who they claim to be (for example, via password + SMS code).
Authorisation – determining which data or applications someone may use.
Monitoring – insight into who accessed what and when, important for audits and compliance.
A concrete example:
A new employee starts in the HR department.
HR enters the information into the HR system.
IAM automatically ensures the employee access to email, intranet, and the HR tool.
If the role changes, the rights are automatically adjusted.
Upon departure, all accounts are immediately closed.
IAM and HR-driven provisioning
A modern IAM solution works HR-driven. This means that the HR system is the source of truth. As soon as HR changes something (e.g., new employee, role change or departure), IAM follows automatically with the correct adjustments in all connected systems.
This prevents errors, saves time, and fits perfectly with how organisations work.
The role of IAM in Zero Trust Security
More and more organisations are switching to a Zero Trust model: no one gets standard access, every access is checked. IAM forms the foundation for this. Without well-implemented IAM processes, Zero Trust is simply impossible.
IAM in practice: where do you start?
If you want to start with IAM, it is wise to begin with:
Inventory – which systems and data do you use?
Define – what roles and rights are there within your organisation?
Automate – let your HR system be the engine for access management.
Monitor – ensure you always have insight into who has access (and had).
Conclusion
Identity & Access Management (IAM) is much more than an IT solution: it is a crucial part of safe, efficient, and compliant working. With IAM, you provide employees with the correct access immediately, protect sensitive data, and save HR and IT a lot of time.
IAM is no longer a luxury but a basic requirement for every modern organisation.

How do you apply AGDLP in a hybrid Entra/AD environment? (And why you shouldn't want to anymore)
Short answer: preferably not. AGDLP (Accounts → Global groups → Domain Local groups → Permissions) is a concept from the era of manual management. The entire nesting construction exists for one reason: to allow a human to assign permissions with as few mouse clicks as possible. As soon as an agent assigns group memberships directly based on HR data, this reason disappears and only the complexity remains. Moreover, in a hybrid environment, this complexity actively works against you, because Entra ID completely ignores nesting for licences and app assignment. In this article, you can read how AGDLP works and why it was once smart, where it breaks down in a hybrid environment, and what the modern alternative looks like: direct memberships, managed by automation.

How do I set up role-based access control (RBAC) and least privilege for a municipality?
Start with the roles in your HR system and map them to roles, not to individual permissions per person. Group each role with precisely the access required for the job, adhering to the principle of least privilege. Manage these roles centrally and let an orchestration layer automatically assign and revoke them. This keeps access predictable, limited and demonstrable.
